One year after putting together the NFL's worst record, the Indianapolis Colts are headed to the playoffs.
Joining them Sunday were the Cincinnati Bengals, finishing out the field in the AFC.
The Colts (10-5) equaled the 2008 Miami Dolphins as the only teams to win at least 10 games after losing 14 or more the previous season. Top overall draft pick Andrew Luck completed a 7-yard touchdown pass to Reggie Wayne late in the fourth quarter for a 20-13 victory at Kansas City.
Cincinnati (9-6) qualified for a second straight playoff berth for only the second time in team history, edging Pittsburgh 13-10. The Bengals have never gone to the playoffs in successive years that did not involve a strike-shortened season.
Minnesota's 23-6 win at Houston prevented the Texans from earning home-field advantage throughout the AFC playoffs. AFC South champion Houston (12-3) still can get that by winning at Indianapolis in the season finale.
Baltimore clinched the AFC North by beating the New York Giants 33-14, sending the defending Super Bowl champions to the brink of elimination. Washington will win the NFC East by beating the Cowboys next week. But Dallas takes the division by winning that game at Washington.
Luck finished with 205 yards passing to break Cam Newton's year-old rookie record of 4,051 yards in a season. Luck, who has 4,183, also extended his rookie record for fourth-quarter comebacks to seven by leading his team downfield in the closing minutes.
Other NFL records established:
• Minnesota rookie kicker Blair Walsh broke the league mark for 50-yard-plus field goals in a season. Walsh kicked a 56-yard field goal in the second quarter against Houston, giving him a record ninth field goal of 50 yards or more.
• Redskins kicker Kai Forbath set the NFL record for consecutive field goals to begin a career with 17 straight.
• Dallas' Jason Witten broke the record for catches in a season by a tight end. Witten's 103rd catch of the season came in overtime against New Orleans. Tony Gonzalez held the mark with 102 catches for Kansas City in 2004.
